      <h1>Web Server</h1>

<p>The standard library <a href="https://golang.org/pkg/net/http/"><code>net/http</code></a> provides a powerful set of tools you can use to make your own web server.</p>

<p>See my Lanyon project: <a href="https://github.com/mkaz/lanyon">https://github.com/mkaz/lanyon</a> for a more complete server created in Go which converts markdown to html.</p>

<pre><code class="language-go">package main

import (
	&quot;fmt&quot;
	&quot;log&quot;
	&quot;net/http&quot;
)

func main() {
	// associate URLs requested to functions that handle requests
	http.HandleFunc(&quot;/hello&quot;, helloRequest)
	http.HandleFunc(&quot;/&quot;, getRequest)

	// start web server
	log.Println(&quot;Listening on http://localhost:9999/&quot;)
	log.Fatal(http.ListenAndServe(&quot;:9999&quot;, nil))
}

// basic handler for /hello request
func helloRequest(w http.ResponseWriter, r *http.Request) {

	// Fprint writes to a writer, in this case the http response
	fmt.Fprint(w, &quot;Hallo Welt&quot;)
	return
}

// this function simply serves up the file requested, or
// an index list if a directory is requested
func getRequest(w http.ResponseWriter, r *http.Request) {
	file_requested := &quot;./&quot; + r.URL.Path
	http.ServeFile(w, r, file_requested)
	return
}
